To U, whom it may concern:

Be it known that 1, HA RY E. DADE, a citizen of the United States, and a'resident of Canaan, in the county of Litchfield and State pfConnecticut, have invented certain new and useful Improvements inBinders, of which the following is a specification.

This invention relates to improvements in bindersin 'which sheets areadapted'to be held reinovably in place, and more particularly tosuch asare designed for use as loose I leaf lodgers.

The invention relates to a novel arrange' ment formoving' to and fro andlocking in place the strips of the binder.

It also relates to GeltfllIlDOVGl means emp yed to lock the covers ofthe binder closed.-

It also relates to certain structural features and their arrangementhereinafter 2O pointed out.

In the accompanying drawings, forming part of this specificatimi, and inwhich like reference-numerals designate corresponding slightly-openedposition.

6 is an end view showing the covers and sheets f n place and a modifiedmeans for locking the,

covers closed. Fig. 7 is a partial longitudinal sectional view of hall abinder wlth one of theexp'ansible strips broken. away and showing insectional plan the modified means for locking the covers closed, whichis illustrated in Fig.6. Fig. is a sectional plan view of amodification. Fig. 9 is a trans verse section on the line 9 9 of Fig. 8.Fig. 16 is a longitudinal section on the line 10 10 of Fig. 8. Fig1.1'is a detail of a inodified 'fornrof the means for locking thecovers.

- Fig. 12 is 'a sectional view of such-modified form of such lockingmeans on line- 12 12 of Fig; :11. Fig. "13 is a transverse sectionshowing a modified means for locking the removable post in place. Fig.14 is a'detail of .the locking means shown. in Fig. 13, and Fig.

15is a perspective view of the keeper hereinafter described.

Referring now more. particularly tojl igs y 1 to 5- of the drawings, 1and- 2 are the upper and lower strips of the binder, provided withhinged covers 3 and 4. 5 is the back, which covers the space between theabutting edges of the upper andlower strips land 2.1 These :parts arepreferably made of cast metal..

The back is provided with a central rib 6, to,

which is rigidly secured guides 8- and which work the slide-rods 10 and11'. Se cured to the slide-rod 10 is a cross-head 12, to which andto therespective strips are pivotally" connected links 13 and 1 4. This,

cross-head 12 is shown connected to slide rod 10 by a screw 15. Rod 11carries a crosshead 16, secured to it by screw 17. 18 and.

19 are links pivotally connected to the endslower strips 1 and 2,respectively. Rod .10 carries a threaded extension 20, which works in athreaded rotatable tube21. This .tube. is journaled at one end in anangle-bracket "22, fixed on the rib 6 of the back 5 by screws 23. "It isjournaled at its other end in a 'cas ing-24, which has a tongue 25 fixedto the rib 6 by screws 26. Rod 11 carries a thread-, ed extension 27,similar to the extension 20, and which, works in a threaded tube 28,similar to tube 21 and similarly journaled. The ends ofthese tubes are suared, so as to receive and be operated by akey. These threaded tubescarry. intermeshing pinions 29 and'30, located inside of the casing. 24.

It will be seen that by the arrangement'described when either ,of thethreaded tubes 21 or 28 is rotated by the key the other tube is rotatedin the opposite direction, so that the rods 10and 11 move in oppositedirections. This causes the cross-heads 12 and "16 to move toward orfrom each other, according i to the direction in which the key isturned.

.01 thecross-head 16 and to the upper and I When these cross-heads movetoward each other, the upper and lower strips 1 and 2 are moved towardeach other. When the crossheadsare'cansed to move from each other, theupper and lower. strips are moved from each other, the back alwaysmaintaining its central position. The cross-heads 12 and 16,

with their links, constitute toggles for the movement of the'upper andlower strips.

The strips Land 2 are provided with four fixed telescopic posts 31, 32,33, and 34,, designed to engage holes in the sheets 35. 36 is aremovable telescopic post which extends through an aperture 37 iii-thestri n 1. and into be detached from the fixed posts.

the latter. The post 36 is tubular and is provided with an internalspring 39, tending to extend the post. 40 is the head of the post. Thispost 36 extends through closed holes 41 inthe sheets 35 and musttherefore be removed frorn the binder before the sheets can 7 and 42 arethe pintles for hinging the upper cover 3 to its strip 1..

the spring within the post projects the post above the opening 37,whereupon thepost its outer end provided with an extension 44, may bereadily removed. The pintle 42 has which when the pintle is 1'4 itsinnermost position enters a slot 45, formed. at one end of strip 1. (SeeFig. 2.) The. lower co -er 4 is secured in place bt' a pintle 46, whichis arranged and constructed in a similar manner to pintle 42; but sinceit has no otlice to perform with reference to the removable post it mayextend the full width of the binder. The pintle 42 is retained inposition against. unauthorized removal by a keeper 47, which worksinside of the upper strip 1 and is guided. and retained in. positionagainst the side of the casing 24. The keeper 47 con sists of a flatbody portion 49, which slides just outside of and against the side ofthe easing 24. The keeper is provided with .a tongue 50, extending atright angles to the body portion 49, entering the casing 24 at one'endjust beneath its top and above a pin 51, passing through the casing. toguide and retain the keeper in place. Secured to the inner side of thebody portion 49 of the keeper is a wing portion 52, having a finger 53turned over at a right angle. 48 is a keeper similarly constructed andarranged. When the stack of sheets is in place in the hinder, thelingers of the keepers, such as 53, rest on the top and bottom of thesheets, and the body portion, as 49, of the keepers projects beyond theextensions, as 44, of the pintles, assuming that the upper and-lowerstrips are in their normal working position and pressing against thesheets.

-When the parts are in this positiomthe pintles cannot be withdrawn,because they are retained in place by the keepers. In order to withdrawthe pintles, the strips must be separated far enough to bring theprojecting ends, as 44, o'l' the pintles beyond the body portions 01 thekeepers, whereupon the pintles maybe drawn back. Thus when the sheetshave been inserted in the binder and the post 36 has been inserted andlocked against removal by sliding the rod or pintle 42- over its headthen the mere contracting They pass through holes formed in the bosses43 on strip 1, and pintle -lower strips, respectively.

The tongue 50 serves Likewise when the strips 1 and 2 are expanded therod or pintle 42 is unlocked automatically. Therefore the means forlockingsaid rod or pintle in place is automatically controlled by-theansion "and contraction of the binder. l i

The locking nieans rnay be considered as cornprising-both the pro ectingend 44 of the rod or pintle 42 and also the keeper 47, adapted to engageit. Nhen the binder is expanded, the keeper retains a relatively fixedposition, similar to that of the back 5,while, on the other hand, therod or pintle 42 and its extension 44 move with the binder-strip 1 awayfrom the keeper 47. The keeper 48 retains a similar position relativelyto the binder;

Then the bin der is contracted and after bfinging the extension rod intolocked position, the strips 1 and 2 engage the endsof the keepers 47 and48, so as to press the fingers 53 against the bound sheets. The keeper48 has no othce to perform in the construction shown in Figs. 1. to 5and now being described. It does have an office to perform withreference to Figs. 6 and 7 and 11, as will hereinafter be explained. 54and 55 are latching-plates which work back and'forth in the upper andWhen they are in their forward positions, they enter recesses 56 and 57in the upper and lower covers 3 and 4, respectively, for the purpose oflocking the covers in their closed position. These plates 54 and 55slide in the bosses through which passes the removable post 36. Plate 54has two holes 58 and 59, and plate 55 has similar holes for the purposeof receiving the removable post 36. I When these latching-plates 54 and55 are in their inner position, as shown in Fig. 3, the coversare-rcleasedand may be worked on the pintles. W'hen these latchingplates54 and 55 are in their forward position, as shown in Fig. .4, they enterthe recesses 56 and 57 of" the covers and lock them to the upper andlower strips and hold them rigidly in closed position. Thelatching-plates 54 and 55 are thus locked in their forward or intheirrear position by the removable post 36. If it is not desired to usetheselatching-plates 54 \and 55, they will be moved to their rearposition, where they willnot interfere with the ren'iovablcpost 36 orthe movement of the covers and wl'iere they will be heldout of the way.These latching-plates are provided with stops, such as 60, to preventthem from l'alling forward out of the recesses in which they work. Inthe arrangement as shown in Figs. 3 and .4 these latching-plates 54 and55 move by gravity out ol engagement with the covers when the removablepost has een Withdrawn; but they may be otherwise actu ated. The back 5has turned-up port ions 61 and 62, which embraccthe ends of the strips.

Referring now to Figs. 6 and 7, the pintles 42 and 46 instead of havingextensions like.

extensions 67 and 69 are designed to enter recesses 70 and 71,respectively, in two outeIt .edges of thecovers'at the rear, so as tolock the covers to the strips 1 and 2 and hold them in ,closed position.Thus these extensions on the pintles accomplish the function of thelatching-plates 54 and 55, (shownin Figs. 3 and 4,) and theselatching-plates. would not betneeded in the arrangement shown in Figs. 6and 7. In Fig.6 keepers 47 and 48 lock the pintles in positionandagainst withdrawal.

en extensions 67 and 69 are in engagement with the recesses 70. and ,71,the exten= sions 66 and 68 of-thepintles are 'on the inner sides of thekeepers and the keepers prevent the withdrawal of the pintles. When thekey has been applied to separate the strips, the

extensions 66, and 68 are released from the keepers, so that'the pintlesmay be withdrawn to disengage the extensions 67 and 69 from the recesses70 and 71. -When it is de sired to lock the binder without looking thecovers closed, then the pintles will be insert ed so that the extensions67 and 69 will project behind the keepers, as shown in Figs. 6

. and 7. i In this position the short extensions 66 and 68 will be clearof the recesses 70 and 71 and willnot interfere with the movement ofthe-covers, as shown in Figs. 6 and 7 Referring now to rigs. 8, 9, and10, these figures show a modified arrangement for moving the strips 1and 2 to and from each other. 72 and 7 3 are two reciprocatingrack-bars. The eeth of bar 72 meshes with pinions 74 and 75, carried onthe back 5. The teeth of bar 73 meshes with pinions 76 and 77, carriedalso on the back 5. 78 and 79 are two r'ackposts rigidly secured tostrip 1 and. meshing with piuions'74 and 75, respectively. 80 and 81 aretwo similar rack-posts secured .to strip 2 and meshing with pinions 76and 77, respectively. 82 and 83 are guides fixed on the'back 5 for thebars 72 and 73. Bars 72 and 73 are provided with. threaded tubes 84 and85, respectively. In these tubes work screws 86 and 87, carrying meshinggears 88 and 89. one of the gears 88 or 89, the bars 72 and 78 v97,fastened in the upper strip 1.

When the key is applied to rotate are moved longitudinally'in oppositedirec tions, thereby rotating the pinions with which they mesh andactuating the upper and lower strips. When the key is turned in onedirection, the strips are moved toward each other. WVhen thekey isturned in the apart.

Referring now to Figs. llland 12, 90 is a latching-plate having a handle103 working opposite direction, the strips are moved back andforth inthe strip 1 and operating to enter a recess 91 in the upper cover andlocking-plate 54 in Figs. 3 and 4. Latching-plate 90 in Figs. 11 and 12has back and front t closed in the same way as does the latchnotches 92,in which the pintle93 enters to lock the latching-plate in forward orrear position. The pintle93 is of the same 'constructionas' the pintle42, (shown in Fig. 2,) except that its inner end; is arranged to engagethe notches in the latching-plate 90. I

en the arrangement shown in Figs. 11 and 12 is used, there would be twolatching-plates 90, one for each .strip, and the removable post' wouldnot be used. Fig. 11 shows 110W the removable post might be dispensedwith and the latching-plates for the covers still be locked in place.

Referring now to Figs. 13 and 14, 94 is a removable post having the samelocation and purpose as the removable post 36. in Figs. 1, 2, 3, and 4.)The removable post 94 has a notch 95 at its upper end, which is engagedby a latch 96, pivoted on the screw The latch 96 is provided with a pin98, arranged to be engaged by a lug 99 on the reciprocating rod 10.Latch 96 is provided witha spring 100, which tends to keep the-latch inthe position in which it engages the removable post.

hen the binder is unlocked, the movement of the rod 10 actuates thelatch 96, thereby releasing removable post 94, whereupon the latter maybe withdrawn from the binder.

'It may sometimes be desirable to remove the (Shown invention. Forexample, the extensions 20' and 27 and the'meshing tubes 21 and 28,respectively, may have their threads so arranged'as to cause the rods 10and 11 to move in the same direction. In-this case oneof the toggleswould be reversed and'the upper and lower strips would be actuated toand from each other in the same manner as al- 1 ready described.

It is to be understood that the invention is not limited to the preciseconstruction and arrangement shown in the drawings.
